Brief Summary

The goal of this clinical trial is to study the effects of using an internet-based cognitive behavioural therapy (iCBT) program and exercise in chronic knee patients with psychological distress. The main question\[s\] it aims to answer are:

• What are the effects of a combined iCBT and standardized exercise program on pain and function in chronic knee pain patients with psychological distress
• What are the effects of a combined iCBT and standardized exercise program on depression, psychological distress, physical function, quality of life, and quadriceps muscle strength in chronic knee pain patients with psychological distress
• Do a combined iCBT and standardized exercise program significantly improve pain and function in chronic knee pain patients with psychological distress compared to a control group?
• Do a combined iCBT and standardized exercise program significantly improve depression, psychological distress, physical function, QoL, and quadriceps muscles strength in chronic knee pain patients with psychological distress compared to a control group? Participants will be allocated randomly to either intervention group or control group. Intervention group will be given iCBT, exercise and educational program, while the control group will be given exercise and educational program only. Researchers will compare both groups to see if the intervention group improves much better in terms of pain, function and other outcome measures compared to the study group.

Outcome Measures

Primary Outcomes (4)

• The Single-Item Numerical Rating Scale (NRS)

  Participants will be asked to rate their average knee pain in the past week on a scale from 0 to 10, with '0' meaning 'No pain' and '10' meaning 'Pain as bad as you can imagine'. This will be recorded via online form.

  8 weeks

• 40-m Fast-Paced Walk Test (40-m FPWT)

  A participant will be instructed to walk as quickly but as safely as possible to a mark 10 m away, return, and repeat for a total distance of 40 m. Time of one trial, with turn time excluded, will be recorded and expressed as speed m/s by dividing distance (40 m) by time (s).

  8 weeks

• Step Test (ST)

  This test will be performed while the participant maintains balance on the study limb, then the contralateral foot will be stepped on and off a 15-cm step as many times as possible within 15 seconds. The count of the number of times the participant could step the foot up and return it to the floor over a 15-s interval will be recorded. The test will performed with no hand support allowed. For participants with unilateral knee OA, the test will be performed while standing on the affected side. For participants with bilateral knee OA, the most symptomatic limb will be considered the osteoarthritic limb for the purpose of this study.

  8 weeks

• 30 seconds Chair Stand Test (30s CTS test)

  From the sitting position in the middle of seat with feet shoulder-width apart, flat on the floor, arms crossed at chest, a participant will be asked to stand completely up, then sit completely back down, repeatedly for 30s. The chair will be against a wall. Count the total number of complete chair stands (up and down represents one stand) of one trial. If a full stand is completed at 30s then this is counted in the total. The same chair is used for re-testing.

  8 weeks

Secondary Outcomes (5)

• Patient Health Questionnaire (PHQ-2)

  8 weeks

• Psychological Distress (Kessler 6)

  8 weeks

• Knee Injury and Osteoarthritis Outcome Score Physical Function Short Form (KOOS- PS)

  8 weeks

• Health-Related Quality of Life-Short Form-12 (SF-12)

  8 weeks

• Maximum Isometric Muscle Strength

Intervention Group

EXPERIMENTAL

Participants in this group will be given 8 sessions of a standardized exercise program, a link to access online educational sessions, in addition to internet based cognitive behavioural therapy sessions.

Other: Standardized Exercise Program; Other: Internet based Cognitive Behavioral Therapy; Other: Educational Materials

Control Group

ACTIVE COMPARATOR

Participants in this group will be given 8 sessions of a standardized exercise program and a link to access online educational sessions.

Interventions

Standardized Exercise Program OTHER

Participants will be asked to attend to the department for 8 supervised physiotherapy sessions designed to strengthen lower limb muscles. Eight sessions were chosen as this number should be able to achieve improvements in pain and function. Standardized exercises sessions will be held once weekly in the health center and will be supervised by the researcher. In addition, participants will be requested to perform the prescribed exercises 3 times per week at home, with 1-2 days rest interval between the exercise's sessions. The program is comprised of a minimum of 4 and a maximum of 6 individualized lower limb exercises to be performed 4 times per week (once in the health center and 3 times at home). All exercise programs will include at least 2 knee extensor strengthening exercises, 1 hip abductor strengthening exercise, 1 hamstring strengthening exercise, 1 calf strengthening exercise, and 1 other exercise will be chosen based on assessment findings.

Control Group; Intervention Group

Internet based Cognitive Behavioral Therapy OTHER

This intervention will be given to participants in intervention group. This is a link to access pre-recorded online sessions of CBT. The iCBT link contained eight 35- to 45-minute sessions, designed to be completed weekly, each provided an explanation of a cognitive or behavioural pain coping skill. Session 1 provided an overview, including a therapeutic rationale of CBT, followed by training in progressive muscle relaxation. Sessions 2 through 7 taught brief relaxation skills, activity-rest cycling, pleasant activity scheduling, cognitive restructuring, pleasant imagery, and problem-solving. Session 8 consolidated the learnt and taught strategies for long-term skill use. Each session has to be completed within the same week where the physiotherapy session is given. The researcher has developed a website that contained all the CBT materials.

Intervention Group

Educational Materials OTHER

All participants will receive a link to access online educational material about chronic knee pain. This is a YouTube link that consists of 5 sessions, with each lasting for 5-7 minutes, and is comprised of general information about the following: healthy eating, osteoarthritis and X-Ray, physical activity, the full pain experience, and proper footwear. Participants will be encouraged to access the educational material at their own leisure and pace.
